This section describes existing measures of emotional health and reviews major findings in the field with respect to their relationship with physical health and cognition. The pages are divided into three sections including the following links: (1) Domains. This section will link to a listing of the major sub-domains for each construct; (2) Measures. This section links to specific measures which have been used in each domain and sub-domain; and (3) Description/Samples/Epidemiologic Evidence which links to definitions, brief summaries of the identified measures used, and representative studies with findings using each measure. The emotional domains are listed roughly in the order of the amount of existing epidemiologic evidence connecting these factors to cognitive health.
